A transport plane takes off from a level landing field with two gliders in tow, one behind the other. The mass of each glider is 700 kg, and the total resistance (air drag plus friction with the runway) on each may be assumed constant and equal to 2900N . The tension in the towrope between the transport plane and the first glider is not to exceed 12000 N.

A- If a speed of 40 m/s is required for takeoff, what minimum length of runway is needed?

B- What is the tension in the towrope between the two gliders while they are accelerating for the takeoff?

Express your answer using two significant figures.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
